Getting your domain set up to work with Office 365 can be challenging. The DNS system is nitpicky to work with, and the DNS setup for your domain affects important business activities, like email!

But we can help you fix issues with your domain's DNS setup. The domains troubleshooter will show you any records that need fixing, and exactly what the records need to be set to. You can follow step-by-step help to fix the records at your registrar.
